RESUMO

BACKGROUND: Little information is available regarding the controversial issue of steroid withdrawal following heart transplantation (HT), or instead in the incidence of adverse steroid effects at dosages typically employed in Spain. METHODS: We analyzed the 5-year follow-up records of 1209 patients (82.5% men, aged ≥ 18 years) who underwent HT between 2000 and 2005 and survived at least 1 month in 13 Spanish centers. The incidences of first steroid withdrawal before 1, 3, and 5 years post-HT were expressed as Kaplan-Meier probability estimates. Three patient groups defined in accordance with steroid dosage at 1-year follow-up (0, ≤ 5, and >5 mg/d; groups A, B, and C, respectively) were compared with regard to the incidence of de novo hypertension, diabetes, and bone fractures over the following 2 years. RESULTS: The 5-year incidence of withdrawal was 28%, 21% of whom required reintroduction of steroids. Kaplan-Meier probabilities of withdrawal before 1, 3, and 5 years post-HT were 8.8% (95% confidence interval ([CI] 7.3%-10.7%), 27.8% (CI 25.2%-30.6%), and 30.2% (CI 27.5%-33.2%), respectively. At 1-year follow-up, 9.9% of patients were steroid-free, 28.9% were taking ≤ 5 mg/d, and 61.3% >5 mg/d. The 2-year incidence of de novo hypertension increased significantly (P = .012) from 13.5% to 29.6% to 35.3% in groups A, B, and C respectively. These groups did not differ significantly in regard to the 2-year incidence of diabetes or bone fractures. CONCLUSIONS: Reintroduction of steroids was required by 21% of the 28% of Spanish HT patients who has been weaned from steroids within 5 years of HT. The incidence of de novo hypertension between 1 and 3 years post-HT increased with steroid dosage at 1-year follow-up. De novo diabetes and bone fractures showed no similar significant association.

RESUMO

INTRODUCTION: Malignancy is a major complication in the management of solid organ transplant patients. Skin cancers show a better prognosis than other neoplasms, but not all others are equal: Ideally, patient management must take into account the natural history of each type of cancer in relation to the transplanted organs. We sought to determine the prognosis of various groups of noncutaneous nonlymphomatous (NCNL) cancers after heart transplantation (HT). METHODS: We retrospectively analyzed the records of the Spanish Post-Heart-Transplant Tumour Registry, which collects data on posttransplant tumors in all patients who have undergone HT in Spain since 1984. Data were included in the study up to December 2008. We considered only the first NCNL post-HT tumors. RESULTS: Of 4359 patients, 375 developed an NCNL cancer. The most frequent were cancers of the lung (n=97; 25.9%); gastrointestinal tract (n=52; 13.9%); prostate gland (n=47; 12.5%; 14.0% of men), bladder (n=32; 8.5%), liver (n=14; 3.7%), and pharynx (n=14; 3.7%), as well as Kaposi's sarcoma (n=11; 2.9%). The corresponding Kaplan-Meier survival curves differed significantly (P<.0001; log-rank test), with respective survival rates of 47%, 72%, 91%, 73%, 36%, 64%, and 73% at 1 year versus 26%, 62%, 89%, 56%, 21%, 64%, and 73% at 2 years; and 15%, 51%, 77%, 42%, 21%, 64%, and 52% at 5 years post-diagnosis, respectively. CONCLUSION: Mortality among HT patients with post-HT NCNL solid organ cancers was highest for cancers of the liver or lung (79%-85% at 5 years), and lowest for prostate cancer (23%).
